I think the recruiter are getting trained by calling the candidates as well as managers are also taking many interviews, they are playing around. They took 2 technical rounds before HR and after the HR they are again saying the manager needs to talk to you and the 2 managers called me and after that no news regarding the position and offer letter, They won't release the offer letter please don't try to join this compay it's a total waste of time. Time is precious.
